Item price list:

What is the concept behind OptiTune?

Restoring the connection of an individual who has headphones on with other individuals, through displaying real time visualizations of what the user is listening to.

What is the form?

A 3 inch cylinder that lights up according to the beat of your music.

How does it work?

You can either plug in your headset and have the lights turn on according to your playlist, or take the headset out and have OptiTune visualize the sounds surrounding you.

What materials does it use?

  1. Arduino micro
  2. 3.5 mm audio jack (x2)
  3. 3.5 mm audio cable
  4. 100k resistor (x3)
  5. Porto board
  6. PCB mount pins
  7. Portable USB charger


What needs to be done ahead of time?

  • Create prototype
    • Set up the board with NeoPixel and microphone
    • Sewing the prototype into a badge
    • Constructing circuit and decorate the badge
  • Charge battery pack

Do you need extra batteries?

  • We have decided to use old phone batteries

What goes into your repair kit?

  • Fabric, thread and needle, battery charger

During Process:

First of all, we will document our user experience on using the the optune. And also select a group of testers to try it. We will document the process by vedio and writing notes.

Secondly, we will carry on our stuff and test it in a daily life. We will take notes regularly and also take selfies at different locations. We will be observing other people’s reactions to us playing the Optune, and we will collect  quantitative data like how many times does people inquiry our product.

Crunching the data

How will you structure a debriefing conversation?

  • Meet for a debriefing conversation, and take notes

What will you do with the data and media once you find it?

  • Look for improvements for future iterations
  • What was liked about the device?
  • What was not like about the device?
  • Was the device comfortable?

Where did you place your OptiTune?

We mostly put it next to our laptops when we were working on our projects at school. It was a fun and playful object that made stressful times entertaining.

What did you like about OptiTune?

Looking at the beautiful lights! Especially in the dark when the lights are off, or when you are taking a walk outside. It really is beautiful and exciting to see the music you are listening to.

What did you dislike about OptiTune?

The case, and the wires.

For future iterations we will have a case that can not only keep the device safe and waterproof but can easily be attached to anything.

How was the experience of the observers of your OptiTune?

We were on campus most of the time. So many of the people who passed us by were students. The fun part was when we were visiting the undergraduate buildings and the students would ask us if we had bought them from the OCAD store. Ofcourse, with pride we told them that we had made them as part of our project.optituneposter optizine_p_page_1 optizine_p_page_3optizine_p_page_4optizine_p_page_5 optizine_p_page_6_mg_3127_mg_3086

timesUp is a minimal and stylish wearable timer that is designed to increase the productivity of the user. It can be worn on the wrist as a bracelet or hung from the neck in the form of a necklace. It features a timer which breaks down working time into intervals of 45 minutes followed by 15 minutes of break, or as we call it “play” time. Once the time is up the device notifies the user by a short vibration and blink of an LED. 

The project was developed based on Pomodoro time management technique, introduced by Francesco Cirillo in the late 1980s. The goal of this product is to encourage the users to commit to a set of work and play time intervals and help them maximize their efficiency and minimize the distractions. In addition, taking short, scheduled breaks while working eliminates the “running on fumes” feeling that users get when they have pushed themselves too hard, leading to a more productive day.



The product includes a vibration notification system, an LED notification system, and also a button to activate the commands.

The instructions to use the product is as following:

  • Press and hold the button to Start or Stop the timer.

          – Start is notified as a single vibration

          – Stop is notified as double vibrations

           When it’s time to take a break or get back to work the device will notify you by 3 vibrations and the blink of the LED.


  • Press the button to check the amount of time left on the timer. The LED will flash 3 times:

          – Slowly if within the first half of the interval

          – Fast if within the second half of the interval


  • Press the button to toggle between Work time (45 minutes) & Play time (15 minutes)

          – Work mode is displayed with two slow blinks of the LED

          – Play mode is displayed with two fast blinks of the LED



For many people, time is an enemy. The anxiety triggered by “the ticking clock”, in particular when a deadline is involved, leads to ineffective work and study behavior which in turn elicits the tendency to procrastinate. The Pomodoro Technique was created with the aim of using time as a valuable ally to accomplish what we want to do the way we want to do it, and to empower us to continually improve our work or study processes.

The Pomodoro Technique is founded on three basic assumptions (Francesco Cirillo):  

  • A different way of seeing time (no longer focused on the concept of becoming) alleviates anxiety and in doing so leads to enhanced personal effectiveness.  
  • Better use of the mind enables us to achieve greater clarity of thought, higher consciousness, and sharper focus, all the while facilitating learning.
  • Employing easy-to-use, unobtrusive tools reduces the complexity of applying the technique, while favoring continuity, and allows you to concentrate your efforts on the activities you want to accomplish. Many time management techniques fail because they subject the people who use them to a higher level of added complexity with respect to the intrinsic complexity of the task at hand.

In order to develop this project, we considered ourselves as the potential users and thought of our daily challenges and needs in order to build a personalized product. All three of us were concerned with our time and how we manage it. Hence, we decided to build a product that helps us keep a better track of time passage while eliminating the distractions caused by traditional or phone alarms. 

Design and Production Process

Since the goal of timesUp is to minimize the distractions, whether caused by the user or by other people, we wanted the product to be as invisible as possible, in a way that it does not draw the user’s attention towards itself and also does not invite others to inquire about it. This main principle formed many of our design decisions. For instance, there is no visual sign, such as lights, indicating that the device is running, in order to minimize the attention drawn by the device. However, the user can still check the time passed or make sure the device is running by pressing the button and watching different blinking modes of the LED. 

In order to better user test different forms of the product and come up with the best design solution as we compare them, we decided to build three distinct products, while keeping the aesthetics, design choices, and functionality identical among the three objects. This gave the wearable flexibility and comfort along with ease of use. We built a bracelet and two different necklaces.






We used 3D printing to build the prototypes. The main reasons behind choosing 3D printing was firstly because of its rapidness and low cost, which enabled us to do multiple iterations of the product and try different forms, before coming up with a final solution. Secondly, the light weight of the plastic made it a perfect choice for the material of this particular wearable product, as comfort should be a key feature of both the bracelet and the necklace.

The 3D printer we used was the MakerBot Replicator 2 and the polymer material filament was PLA (Poly Lactic Acid). After creating a range of textural vocabulary, we printed multiple disks with different textures and stacked and glued them on top of each other. There is a little slit cut on the side of the products that allows USB connection, in case the battery dies in the middle of a work session or in case a new code should be uploaded to the microcontroller.

The artistic details/forms of the product were explored in Autodesk Fusion 360. These were based on contemporary jewelry, which worked to our advantage since we were able to use the device in our everyday lives without the device attracting much attention in public workspace.













The circuit used in timesUp is identical among all the three prototypes. It consists of a mini vibrator motor, an LED, and a button, all connected to Gemma microcontroller. The reason behind choosing Gemma was mainly because of its small size and low cost. Although some features of the Gemma such as not having a serial port made it difficult to debug the code, it overall provided the functionality that we were looking for. In addition to the above components, we also used diodes to protect the components against reverse or negative voltage, transistors used as amplifiers, and also two 1K resistors. 



Here is a complete list of all the components used:

User Testing Process

After building and integrating the circuit into the 3D printed objects, we tested the timer by setting the alarm to vibrate after one-minute intervals, in order to make sure that the timing and notifications work perfectly. We then set the alarm to vibrate 45 minutes after starting the test, indicating the start of the break, followed by another vibration after 15 minutes, showing the end of the break. Since the goal of our product was to keep the user focused and away from any possible distractions, we took notes and wrote down any significant comments on a piece of paper during the 15-minute breaks. After the user testing session was done, we filled up the following questionnaire:

Overall, the product felt comfortable and familiar. Although some of the notifications were confusing sometimes, the overall experience was smooth and straight forward. The bracelet version was more reliable in term of detecting the vibration notifications compared to the necklaces, as we noticed that it was sometimes hard to feel the vibrations of the necklace. Unexpected challenges were to isolate from water as the enclosure is firm but permeable. 

The link above contains the results of our responses to the user testing questionnaires. The image below also shows some of the highlights of these results.


Instructions Handout


Challenges, Outcomes, and Future Iterations

The timesUp wearable is designed to help with time management and increasing focus level while working or studying. Although we found it challenging to commit to the designated time intervals at first, we realized that this product could help us gradually increase our efficiency and minimize distractions, when using it over a longer period of time.

The main challenge was to integrate the commands such that the product is equipped with different functionalities, while maintaining simplicity. It was challenging to play with various functionalities that the combination of a button, LED and vibrator could provide, in a way that they become intuitive to the user after a while.

The other difficult aspect of the project was the size of the product. The goal was to make the product simple, light, and relatively small. Hence, we spent a considerable amount of time carefully soldering the delicate components we were using and stacking them on top of each other such that they occupy the minimum amount of space.

For future iterations, we would like to make the On/Off switch on the gemma accessible to use. This would make the interactions with the device simpler as we could save the “holding button” action to switch between work and rest mode, and use the “pressing” action to check the time. A charging module or a disposable battery would make it easier for the user to keep the device running as the gemma doesn’t charge batteries. In addition, housing the button inside the device and using the the whole display to touch and press it could give a more sleek look to the product, as pressing the button is the only interaction needed from the user. Lastly, insulating from the water seemed relevant to do for the wrist piece, as it is in the splashing radius when washing hands/dishes.

Yes I Can Box

The ‘Yes I Can Box’ is a simple tool for reducing anxiety. This portable device is intended as a coping mechanism, providing self soothing immersive light on demand at the push of a button. It delights the eye with a range of colour washes and patterns, and this delight is amplified when shared with others.

The concept is both a practical solution during and from the outcome of our research. Our team consolidated a direction for hardware relatively early in the twelve day cycle, but experienced increasing tension while trying to reach consensus about the marrying of concept to code. Frequency of events and what those events represented, consistency of home vs school network access, and trying to do justice to the twin eight hour formats, were all factors influencing our struggles. For these reasons, we decided to keep the concept simple, and really focus on the execution of the build parameters — making a rugged circuit and polished portable device, fully functional and ready for our user testing.

While the concept is simple, it speaks to an important issue. Most of us experience some level anxiety on a weekly — if not daily — basis, and we would argue an important factor in mental health is the way we deal with these challenges. The tools we use (psychological, physical, social) are acquired as navigate life. Some are taught to us as children, some we learn from our environment. Some coping tools are healthy (talking with friends, exercise), while others are not (substance abuse, self harm).

We are not psychologists and have neither the experience nor the visions of grandeur to promote this as a ‘solution’. This project is just a small gesture both to ourselves and to the world — a simple and delightful portable device that elicits a real (if fleeting) moment of comfort and pleasure.



project description, including overview of object and intended context and users

Human thinking is accompanied by a variety of subjective experiences, including moods and emotions, metacognitive feelings (like ease of recall or fluency of perception), and bodily sensations. A new interpretation is given to the controversy over emotions by identifying the conscious differentiating aspect of the emotions with the feelings. Four differentiable feelings are recognized: pain-unpleasantness, pleasure-pleasantness, excitement, and depression. In accord with the Cannon theory, the anatomical seat of these processes is assumed to be projection areas of the thalamus. Pain and unpleasantness are assumed to differ only in degree, as are also pleasure and pleasantness. The characteristic tone of the emotions is supposed therefore to result from these affective components. This would account for the failure to find visceral or behavioral differentia for the emotions, and would not throw the whole burden of differentiation on the perception of the stimulus situation

The relations of emotion and feeling is connected together to formulate and human action these action can be any things such as modes and senses, emotional variations. This project is reaction to daily emotions and feelings.

Devices have a built in charging circuit. So they don’t need extra batteries, but they do need to be fully charged before starting.

For a repair kit we’re going to need:

→ micro screwdriver to unscrew it if needed.
→ electrical tape, in case a connection busts.
→ micro USB charging cable

During Field Testing:

Most of our data collection during will be personal journaling (maybe just one entry). The goal of this box is to help relieve anxiety, so writing a journal entry about how we were feeling, what else is happening in our lives, and how external things are affecting

→ Did we end up using the device for a different purpose that its intended use?

→ Did it actually help us?

What will you do w/ the media collected:

→ Probably throw together a small mini site or blog w/ journaling and pictures.

Build Issues
Some of the issues we ran into code wise were mostly related to libraries not playing nice with one another. Originally this item was going to be networked, but it was discovered that the Adafruit IO rest library intereferred with the neopixels / neopattern non-blocking option due to a re-connection script running the background. A work around is still being looked at. Other build issues were related mostly to switch placement. Because the project flip flopped a bit, considerations on where to put an off switch, have the recharge connection facing out, or a panel button were done somewhat on the fly. But our case design was modular so as a first run, it worked out in the end. There were also some parts related consistency issues around what was available locally. For example: difference in size of Adafruit branded pixel strips and non-branded pixel strips.

Hot Feet

Experiment 5 -Bijun Chen, Masha Karimi, Katie Micak




When faced with the challenge of Experiment 5- multiples, we were most interested in creating a prototype that could be built upon in a practical way. Our goal was to also create something which could have a use beyond the classroom. “Hot Feet” was born out of the spirit of giving. Ideally, this giving would be to those who are unfortunate to spend more time than comfortable out in the cold, namely those that are homeless (though there could be many other applications or users).




Hot Feet is a shoe that offers battery powered heat by closing a simple circuit. It consists of one battery that sends a charge first through the right shoe (which holds the battery) and then sends it to the left shoe, turning on both heating pads found in the insole of each shoe. The circuit is completed when the shoes are put together at two points of contact, positive and negative. After a few seconds both shoes will begin to heat up, and the battery will not be active if this circuit is not closed resulting in neither shoe creating warmth.


In creating Hot Feet we wanted to create a warming shoe that would:

  1. Be simple to use
  2. Ran off of a rechargeable battery
  3. Would be inexpensive
  4.  Could be easily replicated
  5. Inconspicuous in design
  6.  Safe and durable



Our total costs for 3 prototypes is around $220.00, with the highest expenses going towards the shoes and the batteries.

Each person purchased a shoe that reflected their preference. Our hope was to create a prototype that could be integrated into multiple shoe designs regardless of the show structure. The shows purchased were: a running shoe, a winter boot with faux fur lining, and a casual high heel with laces.

img_0653                                       img_0654

Once purchased we each created insoles that would contain the heating pads and created a thin boundary between the pad and the foot of the wearer. All wires were connected using simple sodered connections and conductive thread. We created the switches on the outside shoe, and sewed conductive thread from the inside to the outside of the structure at points were the feet naturally lined up and made contact.  The thread on the outside would be create the connection over both shoes and complete the circuit.





The Connections inside of the shoes were loose. Loose connections inside of the shoes had higher resistance than the actual heating pads ( P = VI = RII ) which resulted in the connections heating up more than the actual pads to the point that the heat was not bearable anymore. These heating pads require a lot of power to run and also their temperature can go as high as 60 C degrees. Running them in series requires less battery usage and also brought down the heating pads temperature to a more bearable heat. Hence we had less energy waste. If the connections are done perfectly, these shoes should function even in rain since the resistance of water over felt (material that the shoes are made out of) is higher than the resistance in conductive fabric and conductive thread. Therefore the currents would still run through the path with lower resistance. The placement of the battery on these shoes were very crucial. our initial design paced the battery somewhere on the outer side of the shoes to make sure no interfering with the comfort of the wearer’s feet. However cold weather also interferes with the battery performance. Our challenge was to find the best location for the battery inside of the shoes where it is still comfortable to be worn. Having the battery inside of the shoe resulted in the battery staying at a temperature range which prevents it from discharging quickly.



First Image shows the parallel circuit diagram and the second shows the series circuit diagram.

POWER In the parallel format there will be a bigger power supplied to both pads. In the series diagram there will be less power supplies. hence the series diagram is more power efficient.

HEAT higher heat produced by the pads due to higher resistance there will be less heat produced by the pads.

MATERIAL Parallel diagram needs at least three points of contact to perform therefore more material to connect/wire the three conductive fabric switches on each shoe. Series diagram needs at least 2 points of contact to perform hence less material usage.

EFFICIENCY In the parallel circuit if one part disconnects the other part still performs, whereas in the series circuit it is required for all parts to be connected and perform ignorer for the entire circuit to work.

Three users would wear the shoes for 16 hours, or two days, for the duration of the experiment. Although the prototype worked correctly, each user had different reported experiences.

Katie’s shoe worked well (at first). Heated up to a comfortable warmth quickly. Was comfortable. Day two the circuit got overloaded and caused a burn on her foot- she had to remove her shoe quickly.

Mahsa had a similar experience. Her shoe worked for quite a few hours before the connections got strained and she also received a burn on her foot, while in public.

Bijun’s shoes worked the whole time. Her connections were sound. Her biggest issue was recharging the battery, which she did do only once. The reason her show was probably successful the longest


SURVEY:    We created this quick survey to cover the main points of Hot Feet.



Did Heated Insoles work?  Yes

How comfortable is the shoe? (1 less comfortable- 10 most comfortable)  8

Did the battery last?  Yes

Did you have to recharge the battery? Yes

If yes, how many times/ how long did it take?  I charged the battery once after the first day of experiment (first 8 hours) were over.

Do you think “Heated Insoles” would work keep feet warm for people spending long periods of time outdoors?  Yes

Did Heated Insoles warm up your feet?  Yes – and my feet stayed warm long after I took my feet apart.

How warm were your feet? (1 coldest – 10 hottest)  7

What would you change?

I would change the material that the insole was made out off. The felt insoles were too thin to hold their shape and were moving around inside of the shoes.

The Connections inside of the shoes were loose. Loose connections inside of the shoes had higher resistance than the actual heating pads ( P = VI = RI 2 ) which resulted in the connections heating up more than the actual pads to the point that the heat was not bearable anymore.

The choice of having the pads running in a series circuit worked well. These heating pads require a lot of power to run and also their temperature can go as high as 60 C degrees.

Running them in series requires less battery usage and also brought down the heating pads temperature to a more bearable heat. Hence we had less energy waste.

If the connections are done perfectly, these shoes should function even in rain since the resistance of water over felt (material that the shoes are made out of) is higher than the resistance in conductive fabric and conductive thread. Therefore the currents would still run through the path with lower resistance.

How helpful was the repair kit?

The repair kit was very handy. It consisted of:

  1. Conductive Thread
  2. Conductive Fabric
  3. Aluminum Foil
  4. electric Tape to go over possible loose connections




Did Heated Insoles work? Yes

How comfortable is the shoe? (1 less comfortable- 10 most comfortable) 6

Did the battery last? Yes

Did you have to recharge the battery? Yes

If yes, how many times/ how long did it take? Once, exchanged to another battery

Do you think “Heated Insoles” would work keep feet warm for people spending long periods of time outdoors? Yes

Did Heated Insoles warm up your feet? Yes

How warm were your feet? (1 coldest – 10 hottest)  8

What would you change?

The number one thing I would change is the material of the insole, the one I had (felt) cannot handle daily wear and tear, it looked very nice before putting into the boots. I guess that is something we have not considered well. Secondly, I would change the style of the boots. I think my other teammates suffered less when they made theirs. Mine is very tall and has no opening, and it makes it extremely difficult to work with the insole and the connection part in the bottom; and for the top connection conductive fabric, it’s easier to work with, but I can feel the wires when wearing those. I believe the better solution to this problem would be to start / hack the boots with a zipper/button or any kind of opening in the back or side.

Using boots is a good idea because they are more likely to be worn during cold weather, with the heating pad.

How helpful was the repair kit?

It is very helpful! Electric tapes were unexpectedly helpful.




Did Heated Insoles work? Yes

How comfortable is the shoe? (1 less comfortable- 10 most comfortable) 7

Did the battery last? Yes

Did you have to recharge the battery? No

If yes, how many times/ how long did it take?  N/A

Do you think “Heated Insoles” would work keep feet warm for people spending long periods of time outdoors? Yes

Did Heated Insoles warm up your feet? Yes

How warm were your feet? (1 coldest – 10 hottest) 7

What would you change?

On the second day the when I put my feet together the heating pads turned on very quickly. After about 5 mins (and once the circuit was broken) I started to feel a slight shock or burn. It was in my right shoe, the same shoe with the battery. So it was a unsafe in its current design.

I would change a lot about construction- probably make the wires stronger or embed them in the shoe. Also create a shoe that was fire resistant.

How helpful was the repair kit?

It was helpful, but I did not use it as I was not confident that my repairs would be safe.




Our results concluded that this type of shoe could possibly be safely, durably and successfully constructed. It could be created to be hooked into existing shoes, or be a whole new shoe in itself. I found this project to be successful simply because we did create a functional prototype that could find legs and multiple uses in the real world.

Project Description

Fluorescence is an investigation into wearable technology: how it is made, how to wear it, and how the public responds to it. The goal of the project is to create a fashion accessory that is aesthetically pleasing, but that pushes the boundaries of ‘normal’ clothing. We created three warm, soft scarves with a technological twist — they light up in the dark.

It was important to the group to create a wearable that was beautiful — something that would inspire joy in the wearer and the people around them. The idea of a flower-shaped scarf grew from a discussion on how flowers respond to light in nature. A photoresistor seemed like the right fit, and we decided on a scarf because it mirrors the shape of an abstract flower —  the bulk of the fabric represents the stem, the LED lights represent the stigma and the hanging tassels are the flower petals.

We did not want to jam technology into something that doesn’t really need it. Instead, we carefully placed the LEDs in a subtle position that accentuates the natural beauty of flowers. There are practical benefits to have LEDs in a scarf: wearers become more visible to drivers when they are walking or cycling at night, and when the petals are ‘pulled back’ the scarf can double as a flashlight. But our focus was foremost on aesthetics. We wanted to create someone attention-grabbing, thought-provoking and at the same time covetable by a wide-range of people.

We made the scarves different colours to match each group member’s personal style. Each member chose the base colour of her scarf and the size and colour of her flowers.  At first, we were all a bit hesitant to jump on the subway and go to grocery store wearing LED lights, but after a few compliments later it became very enjoyable and we all agree that we would like to continue wearing the light-up scarves beyond the scope of this project. Based on the feedback we received, we conclude that the world is ready for joyful light-up scarves.

    • Try to find patterns in our experiences
    • Draw conclusions on how people view and digest electronic wearables.
      • Is it viewed with hesitation and hostility or will people enjoy seeing it?
      • See what sorts of improvements we could make in future iterations

Process Journal

Once we had decided on the scope of our project, we identified the materials that we needed. We bought scarves and fake flowers from Chinatown, a selection of LEDs from Creatron, as well as 7 metres of silicon wire. We already had protoboards, LDRs, resistors, and Arduinos in our kits.

Using examples from the Arduino website, we constructed a circuit on a breadboard using our components, initially using two resistors – one for the LED and one for the LDR. We realized that the brightness of the LED was affected by the 10k resistor, so we decided to remove it.


The selection of LEDs we bought were different colours and created different “effects”, including ‘bright’, ‘super bright’ and ‘diffuse.’ We also planned to use different colours – red, yellow, and white – and tested the different LEDs to see which ones looked best. Ultimately we chose the ‘diffuse’ effect, and we realized that the different coloured LEDs all had different voltage, so we decided to simplify the circuit by using only white diffuse LEDs.


To create the “light bulb” in the flower we soldered 50cm of silicon wire to each of the white LEDs, and then put a blob of hot glue between the legs of the LED so that the positive and negative currents would remain separate. We soldered 50cm of silicon wire to the LDR as well. We then replicated the circuit from the breadboard onto each of our protoboards which we had cut in half to fit inside the pocket in our scarves.

We split the flowers into “left” and “right” sides, two flowers for each side. We soldered the negative wires together, and then the positive wires together, for both flowers on each of the sides. We then soldered these wires to the protoboard to complete the circuit. We secured the connections with electrical tape.


After we had finalized our circuits, we started “building” on the scarf. We had two scarves each which we cut in a parallelogram shape, as per our design, and used the second scarf to cut out “leaf” shaped pieces which were sewn to the first scarf to create texture.


We then sewed the wires of the flowers into the scarf to hide them. We sewed the LDR wire into the scarf as well, but placed the LDR in a visible location near the bottom, where the scarf would hang around our neck. We chose this placement so that the LDR would not get obstructed by our hair or bags, and would be able to sense the brightness of the space we were in.


Finally, we attached the USB battery pack to the Arduino to test that everything was working.


When it was confirmed that the circuit was responding to external brightness, we were satisfied with the technological development of the scarves, and moved on to our user testing phase. Our results are below.

LED fashion is becoming a popular topic in the fashion world.  We were inspired by “Cute Circuit” and also Ronnie Brust’s designs.

“With great pleasure comes great responsibility” – Brust.

Fashion pieces such as our scarf and Ronnie Brust’s designs need maintenance because they use an external power source. It was interesting to go through his website to see that he sells power banks with his pieces. He also has a Product Care Instructions page

Project Description and Overview:
The very fact that our final project for this course required focus on wearables/portables that would be carried with us and taken into the real world, brought about numerous fun ideas and thoughts. From s
oft cushioned pocket hand-warmers to a digital pet, Tamagotchi, to a brain relaxing sensor inspired by deep breaths, and finally to conductive skin tattoo technology, we thought of it all!

However, the group, after much brainstorm and deliberation, decided to develop the conductive tattoo idea further. We did a lot of in-depth research while weighing the possibilities, given the time constraints and other circumstances. The conductive tattoo concept posed multiple challenges and issues, but it inspired us to create a whole new product, our very own musical instrument, Skynphony (skin+symphony=Skynphony).

Skynphony, represents a piano, worn on the arm that is touch responsive to play musical notes. The overall prototype consisted of an arduino setup on a protoboard attached to a powered battery, which was then integrated into a mock-up of black felt with conductive copper tape strips (denoting 7 music notes in C major scale – C, D, E, F, G, A, B), that fit perfectly on our arm. Three pairs of conductive gloves were made as well. They were used to press firmly on the copper strips that emitted sound.

The Syknphonist’s then went out into the world, solo and in groups, with a Play Me sign, the intention being, to invite the public to interact, engage and perform.

Final Circuit Diagram:

Final Code:
The code was fairly simple. We set up an array that contained the sound frequencies of each key. We then setup pins 2 to 8 to be those keys. When the circuit on any key was completed, the corresponding frequency from the array was sent to the buzzer that would give it a distinctive sound. We eliminated the use of resistors by making all the pins PullUp pins. That made the circuit easier to build and repair.

User Testing Materials:

User Testing Plan:


  • What needs to be done ahead of time?
    • Prepare regular gloves with conductive fabric on finger
    • Cut protoboards into 3 parts for each of us
    • Create a “Play Me” sign
    • Rent GoPros from A/V for documentation. Ensure the memory cards have no prior footage and the batteries are charged
    • Charge all external power supplies
  • Do you need extra batteries?
    • Yes
  • What goes into your repair kit?
    • Copper tape
    • Conductive fabric
    • Extra buzzers and wires for trouble shooting
    • Double-sided tape
  • Be sure to take “before” photos.

During (optional)

  • Do you need to collect information during the testing?
    • Yes. A ‘User Survey’ would be created to gauge how people react, how did they play, what types of questions did they ask, their response, etc.
    • Compare levels of interaction according to “affordances” and how obvious it is that you’re allowed.
  • Do you want the users to journal, take notes, write down significant experiences when they happen?
    • Ideally, yes.
  • Are you capturing any photos or videos of the user experience? If so, how? And how can you make this consistent across all 3 users?
    • Go-Pros with chest attachment
    • If we choose to have ‘busking hours’, we can set camera up on tripod

End of Session Reports

  • You are running this test for two days. Create a survey / form using google forms for users to fill out at the end of their days. You will end up with 6 entries (3 users x 2 days.)
    Potential Questions –

    • How separate did your body feel from Skynphony?
    • Did Skynphony influence your behaviour? How?
    • Did Skynphony influence the way people interacted with you? How?
      • How many people initiated playing with Skynphony with a ‘play me’ sign?
      • How many people engaged with Skynphony while you were just walking by?
      • How many people initiated playing with Skynphony while Skynphonists are in a group, vs solo?
      • Should we dress up our arms like an instrument?How effective was Skynphony as an interaction?
  • How much creativity does Skynphony allow those playing it?
  • Was the user interface of Skynphony engaging and simple to use? Did it make people come back for more?
  • What were the reactions of those who engaged with it?
  • Does the overall product or the next iteration have the potential to be sold in the market?
  • Is there a better or more efficient way to execute Skynphony?
  • What have people gained from interacting with Skynphony?

Crunching the data

  • How will you structure a debriefing conversation?
  • What will you do with the data and media once you find it?
    Once we have the results of the ‘User Survey’ we can collate and analyse the information we receive and further discuss how we can improve the overall prototype and potentially turn this into a robust product that can perhaps be sold in the market.

Summary of the Overall Process:
The overall process needed to be well thought out and one that could be executed with ease. Our initial ideation consisted of conductive tattoo’s on vinyl material that would stick to our arm. However, since that posed multiple challenges and we wanted to create a product we could ‘own’, we agreed on Skynphony. The name emerged from the evident connect, skin+symphony=Skynphony.

We started by creating some rough sketches of the various possibilities and considered the different materials that would work well for the prototype. Since vinyl on skin wasn’t an option any longer, we chose to use felt. Black felt in particular, since the conductive copper tape stood out, making the look and feel very graphic. We tailored the felt to fit perfectly on our arm and 8 strips (ground+7 music notes) of adhesive conductive copper tape were stuck, at intervals, to the felt, representing a piano. Each of the copper tape strips were connected (soldered) to the wires in the circuit that contained the Arduino (with code uploaded) attached to a protoboard. We used an external power supply, a battery, that was placed in a cloth pouch attached to the inner arm of the prototype, that helped run the circuit. Velcro was used to keep all the various components in place. Adhesive conductive fabric was cut and ironed onto the finger tips of three pairs of gloves. GoPro cameras were secured on our chest to record footage. 

Worn directly on our arms, wires and circuitry concealed in the prototype and hardware enclosed in a small pack, Skynphony, emerged successful.

Step-by-step Process Details: 

Construction Process –

 A. Code and Circuit

  1. Tested basic breadboard circuit with DC buzzer and one 2-pin breadboard tactile button. Pin runs through resistor, then to ground. (
  2. Extended basic circuit to three buttons and coded value tones for each
  3. Developed code for seven tones on C major scale
    1. Based foundation of code on:
    2. Frequencies did not translate fully to our buzzer, as the code was meant for a Piezo buzzer and we used the cheap DC ones. Lots of trial and error adjusting frequencies by ear and tuning app:
  4. Code originally had each pin run through a resistor, then to ground. We began mapping out possibilities for a clean, aesthetic circuit layout, prototyping with copper tape. This proved difficult with our circuit, as it was impossible to lay it out without tap crossing over each other to reach ground.
  5. With Kate’s help, we refined code and circuit so that pull-up resistors were integrated into code, and physical resistors were eliminated from circuit. Circuit became simple to arrange in a clean, cascading L layout.
  6. Cascading L layout would be laid out 1 cm above a line for Ground. User would complete circuit between each ‘L’ and ground to sound the note.
    Fritzing diag
  7. Considered using a vinyl cutter for printing out the final cascading L circuit out of copper foil – we decided against this, as we had never used the vinyl cutter before and we were running out of time. Decided to stick with copper tape for final prototypes.

B. Wearable Material

  1. First iteration: painting circuit directly on arms with conductive tape
    1. Cons: conductive paint was not responsive unless thick layer was applied; would need to re-paint circuit on day two; connecting hardware onto painted skin would be challenging, especially with size of Arduino Micro
  2. Second iteration: apply circuit onto vinyl sheet converted into armband
    1. This would be an alternative to directly painted skin, where the transparency would still allow for an interaction that feels close to the skin
    2. The vinyl also proved tricky to use. It was too flimsy to carry the weight of all the hardware attached.
  3. Third iteration: Felt armband
    1. We decided to scrap the transparency of the prototype, and make an opaque, felt armband that was worn like a sleeve. The felt held the hardware fine. 

C. Construction

  1. Applied copper circuits to armbands
  2. Cut protoboard into three; soldered pins onto each cut protoboard for Arduinos; soldered DC buzzers to protoboard; soldered 1 wire per musical note onto protoboard
  3. Attached pocket on the sleeve for portable batteries that would keep Arduino powered through USB
  4. Attached velcro strips onto ends of armband; created felt covering to hide protoboard hardware attached at end
  5. Made wearable gloves: bought polyester gloves from Dollarama and ironed conductive fabric onto the fingertips

Summary of the Testing Process:
The testing process was definitely tedious and time consuming. Although much trouble-shooting and testing was done while we were at the lounge, oftentimes the notes, i.e the copper tape strips would stop working on field, either due to soldering that came apart or a loose component. However, we carried the extra essentials – wire to test the notes, sticky tape in case a component came apart, additional copper tape if it ever peeled off or got damaged.

Troubleshooting Process:
Many times during the field test the sounds would stop. We had a procedure in place for fixing this.
Step 1. Take conductive wire and connect it directly to the Arduino Resistor Pin and Pins (2,3,4,5,6,7 or 8). If the buzzer was activated then move onto Step 2. If the buzzer was not activated the problem was in the code.
Step 2. Run conductive wire across the conductive tape and connect it to the ground to see where the buzzer stops. Fix the break in connection. If the buzzer is not activated at all then move onto step 3
Step 3. Make sure the solder is strong enough and check if the conductive tape is always in contact with the arduino through the soldered conductive wire.

Reflections on your Findings:
All three team members went out into the real world together and then decided to split, using different approaches to invite people to interact with Skynphony. We experienced different reactions. Even though most people were a bit hesitant in the beginning, they had a lot of fun trying it out. When letting people know it was a school project, they were more willing to give it a shot, whereas simply telling them to ‘play my piano’, didn’t necessarily get the response we wanted initially, but was eventually effective as well.

We also observed that different locations and environments, brought about different results. For instance, there was a greater response at places like Nathan Philips Square and Burger King or 100 McCaul but passers by and those about to get on a subway, or then those in a meeting in the VA Lab, were less inclined to interact with it.

However, some of the most common responses that were experienced by us all, was that no one was really interested in playing the sheet music and were happy to play their own tunes, the Play Me sign wasn’t all that effective unfortunately and overall, the product was disruptive and got people’s attention. Another common feedback we received, was that it could definitely be a finished product launched in the market. 

Summary Materials Presented at the Critique:
We presented three Skynphony prototypes to be interacted with. Our our Professor’s and classmates, the Skyphonists sure had fun with it. We also presented a fun video that documented our overall process and experience.
